Hi, This isn't directly mythtv related, but I'm using lvm2 to support myth, and I believe it's commonly used, so I thought folks here might have an idea. I'm also slightly suspicious that lvm may be the cause of a mysterious mythtv problem I'm having.
I'm running ubuntu (5.1 - breezy badger release). I've installed lvm2, but I don't remember installing evms. As far as I can tell from looking at dependencies, evms didn't get pulled in by the lvm2 install. It looks like evms may come pre-installed as part of ubuntu_base (a virtual package that pulls in the basic components of an ubuntu install). I recently upgraded to a 2.6.15 kernel, and started seeing these messages in my dmesg output: [17179593.368000] device-mapper: dm-linear: Device lookup failed [17179593.368000] device-mapper: error adding target to table They get repeated about 10 times. Googling around shows these errors coming from some evms-related problems (possible conflict between evms/device_mapper and other "things" which want to "claim" devices...). It started getting pretty deep, especially since I don't *think* I need/use evms (I certainly don't use it explicitly; but there is some kind of relationship between lvm2 and device_mapper, and between device_mapper and evms and the dependencies aren't clear to me). The solution offered on the evms web site was to apply a patch, but the docs were spotty, it seemed like it was targeted to an early 2.6 kernel, and I suspected it might do more harm than good. With that as background, is anyone else seeing this error? Or know what it means? I can't see any direct consequences, but I always hate to just ignore such ugly stuff in my system logs, and I do have some mysterious problems (with mythtv) for which I'd like to out any relationship with this problem. Does anyone know if I can safely remove evms (when I try it, apt wants to also remove ubuntu_base, which is a virtual package, that supposedly can be safely removed)? Or might there be other consequences of removing evms and ubuntu_base that I need to be aware of? Thanks for any advice. I've also asked for help on the ubuntu forums, but haven't gotten any help there yet.
